The warm nights between the dog days of summer are ideal for night blooming jasmine, Cestrum nocturnum. That is when it disperses its famously sweet fragrance to attract bat and moth pollinators. A bit of humidity, although unnecessary and locally rare, enhances the permeating nature of the fragrance. Some might find such fragrance to be excessive.
Otherwise, night blooming jasmine is quite modest. Those who experience the powerful fragrance at night may be unable to identify its source while visible during the day. Small floral trusses hold several small and narrowly tubular flowers that are about an inch long. Bloom is greenish white or pallid yellow. Simple evergreen leaves are a few inches long.
Therefore, night blooming jasmine works best in the background of more colorful bloom. It will not mind if other flowers get the credit for its fragrance. With regular watering, night blooming jasmine is happy in unseen areas between buildings, and under high windows that lack views. Aggressive pruning only in early spring promotes blooming new growth. Most plants stay shorter than ten feet. Rare white berries are toxic.
